Rominger said a 30-year minimum sentence — which would keep Sandusky behind bars at least until he's nearly 100 — was probably the most the defense could hope for.
Rominger said on WHP radio that Sandusky knows the judge could impose a longer sentence if Sandusky insists he is innocent, but some offenses carry mandatory minimums that are likely to translate into an effective life sentence.
"Why worry about the niceties of pleasing the court when it won't change your sentence?" Rominger said.
Along with Sandusky, prosecutors last year also arrested two Penn State administrators and charged them with lying to the grand jury that investigated Sandusky and failing to properly report suspected abuse. Tim Curley, the athletic director on leave, and Gary Schultz, a retired vice president for business and finance, deny the charges and await trial.
The case led to the firing of longtime head football coach Joe Paterno, who died from lung cancer in January, and the ouster of university President Graham Spanier, who remains a faculty member. Eight legal teams that represent at least 20 victims or other potential civil claimants have surfaced, and Penn State has indicated its desire to settle claims out of court.
After Tuesday's sentencing hearing, Sandusky most likely would be sent to Camp Hill state prison. There, he would be tested and evaluated by Department of Corrections personnel, who will determine which institution he will be sent to.
